The fruiting plants always arise from these rhizomorphs, and by digging carefully around the bases of the stems one can find these cords with the stems attached, though the attachment is frail and the stems are easily separated from the cords. Often these cords grow for years without forming any fruit bodies. In this condition they are often found by stripping off the bark from dead and rotting logs in the woods. These cords were once supposed to be separate fungi, and they were known under the name _Rhizomorpha subcorticalis_. [Illustration: PLATE 27, FIGURE 85.--Armillaria mellea.

Copyright.] =Armillaria aurantia= Schaeff. (_Tricholoma peckii_ Howe) =Suspected.=--This is a very pretty species and rare in the United States. The plants are 6--8 cm. high, the cap 4--7 cm. broad, and the stem 6--8 mm. in thickness. It occurs in woods. It is known by its viscid pileus, the orange brown or ochraceous rufus color of the pileus and stem, and the color of the stem being confined to the superficial layer, which becomes torn into concentric floccose scales, forming numerous minute floccose irregular rings of color around the stem. [Illustration: FIGURE 86.--Armillaria aurantia Schaeff. (=Tricholoma peckii Howe). Cap orange-brown or ochraceous rufus, viscid; floccose scales on stem same color (natural size). Copyright.] The =pileus= is convex to expanded, with an umbo, and the edge inrolled, fleshy, thin, viscid, ochraceous rufus (in specimens collected by myself), darker on the umbo, and minutely scaly from tufts of hairs, and the viscid cuticle easily peeling off. The =gills= are narrow, crowded, slightly adnexed, or many free, white, becoming brown discolored where bruised, and in drying brownish or rufus. The =spores= are minute, globose to ovoid, or rarely sub-elliptical when a little longer, with a prominent oil globule usually, 3--3.5 × 3--5 µ, sometimes a little longer when the elliptical forms are presented. The =stem= is straight or ascending, even, very floccose scaly as the pileus is unrolled from it, scales same color as the pileus, the scales running transversely, being separated perhaps by the elongation of the stem so that numerous floccose rings are formed, showing the white flesh of the stem between. The upper part of the stem, that above the annulus, is white, but the upper part floccose. [Illustration: FIGURE 87.--Tricholoma personatum. Entire plant grayish brown, tinged with lilac or purple, spores light ochraceous (natural size, often larger).]
